RECEPTACLE COVER Victor C. Norquist, Kansas City, Mo., assignor toButler Manufacturing Company, Kansas City, Mo., a corporation ofMissouri Application July 14, 1932. Serial No. 622,397

2 Claims. (01. 220-40) My invention relates to receptacle covers andmore particularly to receptacle covers of a quick acting type.

It has been common practice to use bayonet 5 joints in can covers toenable their rapid and convenient removal and positioning. in coveringrelation. It has been necessary when bayonet joints have been used inthe past, to cut or form slots in the covermember to enable the pintlesof the bayonet joint to cooperate with the bayonet slots. metal byremoving part of the supporting structure. When a particularly tightclosure is desired, the bayonet slots are apt to spring, particularly ifthey are of a pitch to give a high mechanical advantage.

One object of my invention is toprovide a novel bayonet slotconstruction in which no slots are used for the pintle entry.

Another object of my invention is to provide a construction in which thebayonet slots are supported enabling a longer slot of small pitch to beused, thus giving a high mechanical advantage enabling the closure to betightly made.

Another object of my invention is to provide a novel construction inwhich a gasket receiving groove is formed in an expeditious and simplemanner.

Referring now to the drawing which forms part of the instantspecification and which is to be read in conjunction therewith, and inwhich like reference numerals are used to indicate like parts in thevarious views;

Fig. 1 is a perspective view showing a can fitted 35 with a closure ofmy invention.

Fig. 2 is a sectional view taken on the plane 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 2.

Fig. 4 is a perspective view of the closure of my invention. v I

The can 1 is'provided with a neck portion 2 which may be welded, rivetedor secured to can 1 in any suitable manner. The neck portion 2 isprovided with a rolled bead 3 adapted to form a seat for the closure.The neck portion 2 carries spaced pintles 4which are secured to the neckportion in any suitable manner. The closure proper comprises adish-shaped member 5 9 which is made by stamping, forging, or inanyother suitable manner and is provided with a stepped flange 11. Rivetedto member 5 by rivets 7 is an annular member 6 which contains bayonetslots 8. Adjacent slots 8 are depressed or groove-like portions 9 whichform grooves for When this is done, it weakens the the reception ofpintles 4. It will be apparent that the metal of the grooves 9 supportsthe slots at the pintle entering end so that the slots are supportedthere and also at their other ends.

By this construction I am enabled to use a long 60 slot having butslight pitch so that a great mechanical advantage is attained whichforces the gasket 10 firmly against the seat 3. The stepped flange 11coacting with annular member 6 forms a gasket receiving grooveas. can bereadily seen 35 by reference to Fig. 3. A suitable handle 12 is rivetedto the dish-shaped member 5 and forms the operating handle.

In operation, the grooves 9 are aligned with the pintles 4 and the coveris pressed'downwardly 70 bringing the pintles opposite the bayonet slots8. The handle is then turned, causing the pintles to ride along thebayonet slots which are inclined with a degree of pitch. As the pintlesride along the slots, the cover is forced downwardly, forming a tightjoint.

It will be noticed that'my cover is exceedingl simple, comprising buttwo members, namely adished member and an annular member. The handle, ofcourse, does not form part of the 30 cover, inasmuch as the cover may beoperated and used without a handle if desired. It is to be understood,therefore, that I have shown a cover made of two parts only. The ease ofmanufacture, the rigidity and strength of my 35- construction clearlyaremanifest advantages of my construction. The closure formed isexceedingly tight and due to the fact that 'a low pitch is used, thereis no danger of the cover accidentally becoming loose so thatinflammable i101 liquids can be safely shipped in a container, equippedwith a cover of my invention. 7

It will be understood that certain features and sub-combinations are ofutility and may be em I ployed without reference to other features andsub-combinations.

This is contemplated by and is within the scope of my claims. It isfurther obvious that various changes may be made in details within thescope of my claims without departing from the spirit of my invention. Itis, therefore, to be understood that my invention is not to be-limitedto the specific details shown and described.

Havingthus described my invention, what I claim is: j Y

1. A quick-acting closure comprising in com bination an annular memberhaving a plurality of inclined slots formed therein, the metal of saidannular member being pressed to form channelportions adjacent respectiveslots, said channel portions being adaptedto receive pintles and topermit the entry of said pintles into the slots for coaction therewithwhen the closure is in operative position on a container, at dish-shapedmember and a stepped flange formed integral with said dish-shapedmember, means. for rigidly securing said last mentioned member to saidannular member, in telescoped relation thereto whereby said steppedflange is adapted to form a gasket receiving space with said annularmem.-

her and a gasket in said space.

portions beingpositioned laterally adjacent the slot' portions andadapted to receive pintles to permit the entry thereof into the slotsfor coaction therewith when the closure is in operative position on thecontainer.
